proper up keep of the marker will make the gun prefrom like it should as for optimal??? everyone one has there own opinion on that. but proper adjustmenst will do wonders for any gun. best thing in my opinion dont mess with it if it aint broke

AOG has great tweak info, and articles, but only "tweaks" I would recommend, is trying to get a good combo w/ a good low dwell w/ the paint+barrel match=efficient+sound reduction for those quiet kills. also give my way of cleaning ur gun a try (qtip msg above), pretty much only thing u need. Mite want to play around with your trigger if u want, consult info and articles if ur new to this. Last tweak i can suggest is if it works now, dont mess w/ the internals or mods.

Yeah.....your breach should open and close with out a click or hardly any click....You need the Angel tool kit to adjust that. To test if it is out of alignment, just open and close your breach....it should do so without "clicking" or forcing.
